The Password Protection plugin provides a way to safeguard sensitive notes in Obsidian by restricting access with a password. It allows users to lock either the entire vault or specific subfolders, prompting for a password when accessing protected notes. Once authenticated, users can access other protected notes without re-entering the password until they choose to lock the vault again. Additional features include an auto-lock function that re-enables password protection after a set period and an option to prevent closing the password prompt without correct entry. The plugin does not encrypt or modify files, ensuring notes remain unchanged while adding a layer of on-screen privacy.

The Lock Screen plugin for Obsidian brings a new level of security and convenience to your note-taking experience. With this plugin, you can set up a lock screen that appears when you step away from your computer or when your app is minimized on mobile devices. You can also configure the delay before the lock screen kicks in, giving you time to attend to other tasks without compromising your notes' security. Additionally, the plugin allows you to show the lock screen immediately when opening your vault for the first time and via a command palette for quick access.

The Better Canvas Lock plugin allows you to lock the view of your Obsidian canvas, disabling features like zooming, selecting, dragging and dropping, and scrolling. This can be particularly useful when working on complex notes or presentations where unwanted interactions might disrupt your workflow. The plugin also includes a log feature for debugging purposes, although be warned that it may produce some redundant error messages in the console. Additionally, you can still enable limited interaction with canvas cards by focusing on them, which is helpful if you need to adjust the view of a specific card. Overall, Better Canvas Lock provides more control over your Obsidian experience and helps you stay focused on your work.
